Operators and factory engineers already know that there are many technologies that can improve the performance of twin-screw extruders. However, most of these methods are empirical word-of-mouth and do not appear in any equipment manual. They are generally not mentioned in textbooks and technical papers. But sometimes adjusting a few small details will have a great impact on […]

The definition of laboratory twin screw extruder Laboratory twin screw extruder is specially designed for the trial-level or entry-level user, or the small-scale production of color masterbatch and some additive masterbatch.  Above picture is the lab twin screw extruder from Nanjing Granuwel Machinery CO., LTD. The Granuwel lab twin screw extruder range is available in 3 models, from GTE16 to GTE25, with screw

What is plastic pelletizer machine? The working process of plastic pelletizer machine is that, first, adding plastic and other auxiliaries to the extruder, and then the materials are melted, mixed and extruded by the plastic granulator at a certain screw speed and temperature. The plastic particles are processed by a specific granulation method. Generally, the plastic pelletizer machine is composed

What is the function of twin-screw extruder barrel? The extrusion system of the twin-screw extruder is a combined type with the screw is a building block structure, and the barrel is also a combined type (the barrel is also composed of several barrel elements). The length of each twin-screw extruder barrel is about 3- 4D, with each barrel

What is TPV? Do you know what is TPV? This kind of material can be made by a twin screw extruder machine and let’s get details about it. Thermoplastic vulcanizate, short for TPV,  has good characteristics of elasticity, compression deformation resistance, ageing resistance, wide temperature range (-60-150°C), and adjustable hardness (25A-54D). Besides that, it is also

The definition of masterbatch The kind of masterbatch you want to produce will influence what kind of masterbatch machine you choose to buy. Before you buy a masterbatch, it is necessary to know about the masterbatch. What is masterbatch? A masterbatch is a plastic formulation that contains additives that are essential for the appearance and performance of

Preparation before Operating Twin Screw Extruder Do you know what should be paid attention to before you start the twin screw extruder? Good preparation can get high-efficiency work. Below are 17 tips that may be helpful for your operation. Co-rotating twin screw extruder 1. Check whether the electrical wiring of Twin Screw Extruder is accurate and

The preface of fault analysis of twin screw extruder Twin screw extruder for plastic is a common plastic mechanical equipment and is used widely. In the daily operation of the extruder, the double screw extruder sometimes has some failures, affecting the normal production of plastic machinery. The following are several aspects we analyze the extruder’s possible faults

What is a twin screw extruder? The twin-screw extruder is developed on the basis of the single-screw extruder. Due to its wide feeding system(volumetric feeder or gravimetric feeder)good mixing and plasticizing performance, exhaust performance, polymer reaction, etc., it has been widely used in extrusion or pelletizing products. Working principle of twin screw extruder: Advantages of twin

Preface Twin Screw screw extruders are used very widely, besides plastic compounding, they’re also used in a wide variety of other industries such as pharma, biotech, food, aerospace and medical manufacturing and, 3D printing field. During the crisis of the Covid-19,the total whole world market for Co-rotating Twin Screw Extruders estimated around US$935.9 Million in
